Bests & Worsts Reviews from Amazon

*review from a licensed professional using these in a barbershop, giving 10-16 cuts per day* would give zero stars if i could, ordered these because my coworkers who use them love theirs. They constantly get clogged, even after cleaning them out, the screws continually come loose and make a horrendous noise, and 2 months later? they don't even turn on. but oh, you can't return after 30 days. don't waste your money.
